No option to make comment appear at top and setting promoted items does not work

I have a couple problems:
1. No option to make comment appear at top.
There used to be a little checkbox saying if you want your comment of your instructable to appear on top. Now, I don't see one.
2. Setting promoted items does not work.
Whenever I set promoted items, it just says 'saving..' and does nothing

Also while i am at it. Instructables needs a undo and redo button. ctrl-z removes paragraphs, not characters, ctrl-y does nothing. I have had to redo paragraphs because ctrl-z messed it up.

Also, i don't want carriage returns to be deleted in my intructables.

I am using windows 7 and chrome.

Instructables is honestly the buggiest website I have ever seen.
